Sharapova, Djokovic look to improve as quarters beckon

MELBOURNE (Reuters) - The dominant duo of Maria Sharapova and Novak Djokovic are both aware they need to build on their already impressive form as they look to gain quarter-final berths at the Australian Open on Sunday.

Sharapova, who recorded 6-0 6-0 victories in her first two rounds, demolished seven-times grand slam champion Venus Williams in the third round on Friday and meets Belgian Kirsten Flipkens on Rod Laver Arena, still looking to improve.

"I think the reason I started so well in this tournament is because I knew that I had to," Sharapova said in reference to her entering the grand slam without playing a competitive match.
